Organic electroluminescent compound and organic electroluminescent device comprising the same

Abstract

The present disclosure relates to an organic electroluminescent compound and an organic electroluminescent device comprising the same. The organic electroluminescent compound of the present disclosure may be comprised in a light-emitting layer, and is effective for producing an organic electroluminescent device having high luminescent efficiency and/or excellent lifespan characteristic.

The invention claimed is: 
     
         1 . An organic electroluminescent compound represented by the following formula 1-3: 
       
         
           
           
               
               
           
         
         wherein 
         R 1  to R 3 , R 5  to R 6 , and R 8  each represent hydrogen; 
         R 9  to R 16  each independently represent hydrogen or deuterium; 
         R 7  represents a phenyl substituted with deuterium or a biphenyl substituted with deuterium; 
         Ar 1  represents a phenyl substituted with deuterium or a biphenyl substituted with deuterium; 
         D N  means that N hydrogen atoms are substituted with deuterium; and 
         N represents an integer of 8 to 26. 
       
     
     
         2 . The organic electroluminescent compound according to  claim 1 , wherein N represents an integer of 13 to 26. 
     
     
         3 . An organic electroluminescent material comprising the organic electroluminescent compound according to  claim 1 . 
     
     
         4 . An organic electroluminescent device comprising the organic electroluminescent compound according to  claim 1 . 
     
     
         5 . The organic electroluminescent device according to  claim 4 , wherein the organic electroluminescent compound is comprised in a light-emitting layer.
